These fragments of rare galactic rock are all unique, set into a scintillating aventurine disc that makes one whole revolution per day.

Across the dial, between 11 and 12 o’clock, is the 60-second tourbillon escapement mounted in a rotating cage majestically supported by a highly-polished, Y-shaped bridge.

Gilded Gouttes de Rosée hands indicate hours and minutes while the central chronograph seconds hand is complemented by a split-second chronograph hand adorned with a shooting star, the pusher for which is integrated into the crown. At 3 o’clock is a 30-minute chronograph counter.

The ensemble of indications is framed within the regal 18k rose gold case.

Turning Astralis Mercury over, the chronograph column wheel and split-second ‘scorpion’ clamps – providing ultra smooth functionality – can be glimpsed through the display back along with a plate engraved with planets which, together with the gold chaton and blued screws, evoke a beautiful night sky.
